DDLGenerator implementation that delegates to another DDLGenerator for all normal object types. For any object type registered through the DBObjectRegistry the calls are instead delegated to the appropriately registered DDLGenerator implementation there instead.

canChangeProperty

Queries the support for setting or changing the given property for a create or update. If the original object is null then the request is to test whether the given property is settable on a new object. If the original object is not null the request is to test whether the given property can be changed, and if so whether the change can be applied by an update/alter or whether a replace/recreate is needed.
